Hannah deposited the same amount of money into her savings account each month after 5 months she had $2,550 into the savings account after 8 months she had $3,300 and the savings account create an equation that models the amount a and the savings account after x months not included interest show your work ever explain how you determine your equation

Answers

Answer:

a = 250x + 1300

Step-by-step explanation:

We have pairs (5, 2550) and (8, 3300)

Find the rate of change:

(3300 - 2550)/(8 - 5) = 750/3 =250

$250 is the amount added to savings account every month

Initial amount was:

2550 - 5*250 = 2550 - 1250 =1300

Since the change is linear and we have y-intercept and slope, we can show the amount after x months as:

a = 250x + 1300

Find the missing side length, N. ​

Answers

Answer : 15

We know these triangles are congruent. To find the missing side, you first have to find out what the scale factor is. To do this you can just divide side QS by side AC, which would give you 2.5.
You would then multiply this scale factor by side BC, giving you side N, which is 15.

We know these triangles are congruent with the missing side, N would be equal to 15.

What is the congruent triangle?

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

We know these triangles are congruent.

To find the missing side, N

ΔABC ≅ΔQRS

AC/QS = BC/RS

2/5 = 6/n

n = 6 x 5/2

n = 30/2

n = 15

Thus, the value of N is 15.

Can someone plz help me on number 4 plz

Answers

Answer: 6:5

Step-by-step explanation:

Let each little rectangle have the dimensions a by b (where a is the length and longer than b, the width). We find that l=3a because there are 3 lengths of a along l at the top of the crate and that l=4b because there are 4 lengths of b along l at the bottom of the crate. In addition, w=2b+a because there are 2 lengths of b and one length of a along w. Therefore, we can find b and a in terms of l and plug them into w=2b+a to find w in terms of l:

l=4b

b=l/4

l=3a

a=l/3

w=2b+a

w=2(l/4)+(l/3)

w=l/2+l/3

w=5l/6

If w=5l/6, l:w=l/(5l/6)=l(6/5l)=6/5

The correct answer is 6:5.

Solve for x.

Answers

Answer: x = 12

Step-by-step explanation:

(180 - 130) + (3x - 6) + (8x + 4) = 180

180 - 130 + 3x - 6 + 8x + 4 = 180

48 + 11x = 180

48 + 11x - 48 = 180 - 48

11x = 132

11x ÷ 11 = 132 ÷ 11

x = 12

The required value of variable "x" is 12 which is determined by the property of interior angles.

What is a Triangle?

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbol Δ.

We know that the linear pair of angles are adjacent angles the sum of their measures is 180°

Since the sum of all interior angles of the triangle = 180°

(180 - 130) + (3x - 6) + (8x + 4) = 180

180 - 130 + 3x - 6 + 8x + 4 = 180

Rearrange the terms of  variable "x" and combine them,

48 + 11x = 180

48 + 11x - 48 = 180 - 48

11x = 132

x = 132/11

x = 12

Therefore, the required value of variable "x" is 12.

If Maria Louisa assumes that the number of vertices in the sequence of shapes follows the same pattern, how many vertices would she expect the 17 shape to have?

Answers

Answer:

103

Step-by-step explanation:

appears to be an arithmetic sequence question where sequence is 7, 13, 19 meaning the initial value is 7 and the common difference is 6 so we'll plug into this formula:

[tex]a_{17}[/tex] = 7 + (17 - 1) · 6

    = 7 + (16 · 6)

    = 7 + 96

'7' because that's the initial value

'6' because that the common difference

'17' because that's the position the question is asking

First we will solve the inequality: [tex]|x| +3>3[/tex]

Adding -3 on both sides

A 5.5-foot-tall woman walks at 8 ft/s toward a street light that is 22 ft above the ground. What is the rate of change of the length of her shadow when she is 20 ft from the street light? At what rate is the tip of her shadow moving?

Answers

Answer: [tex]\frac{8}{3}\ ft/s[/tex]

Step-by-step explanation:

Given

length of shadow =22 ft

height of woman =5.5 ft

speed of woman [tex]\frac{dy}{dt}=8\ ft/s[/tex]

from the figure, we can write

[tex]\frac{22}{x+y}=\frac{5.5}{x}[/tex]

at given instant

y=20 ft

so, using similar triangle properties

[tex]\frac{22}{x+20}=\frac{5.5}{x}\\22x=5.5x+110\\16.5x=110\\x=6.67\ ft[/tex]

Again we can write

[tex]\dfrac{22}{x+y}=\dfrac{5.5}{x}\\22x=5.5x+5.5y\\16.5x=5.5y\\3x=y\\\text{differentiate w.r.t time} \\3\frac{dx}{dt}=\frac{dy}{dt}\\\frac{dx}{dt}=\frac{1}{3}\times 8=\frac{8}{3}\ ft/s\ \text{away from the woman}[/tex]

The measure of each interior angle of a regular polygon is 120°. Find the number of sides.

Answers

Answer:

6

Step-by-step explanation:

You can memorize these for the smaller shapes

for equilateral polygons:

triangle: 60

square: 90

pentagon: 108

hexagon: 120

Otherwise, I believe the formula is the total degrees in a polygon (s-2)*180 where s is the number of sides.

So the measure of each angle on average would be (s-2)*180/s.

There (s-2)*180/s = 120

180(s-2) = 120s

180s-360 = 120s

60s = 360

s = 6

Answer:

1/3

Step-by-step explanation:

slope is just change in y over change in x

on a graph this can be found by counting the change in units

look at the point at (-3,0)

find the change in y by starting at that point and counting up or down until you reach another point.

the next point (-4,-3) is three units down (change of -3)

now go back to the first point and count left or right until you reach the other point to get change of x

the other point is one unit left (change of -1)

change of y over change of x = -1/-3=1/3

Answer:

slope = 3

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, - 3) and (x₂, y₂ ) = (- 3, 0) ← 2 points on the line
